[Bug] Can't import sources

[LordGyarados]

Version 0.12.5, AppImage on Linux:

When importing sources, i keep getting the following error:

behaviovocabsieve.uncaught_hook:make_error_box:17 - Traceback (most recent call last):
  File "/tmp/.mount_VocabSJenkef/opt/python3.11/lib/python3.11/site-packages/vocabsieve/config/dictmanager.py", line 242, in commit

  File "/tmp/.mount_VocabSJenkef/opt/python3.11/lib/python3.11/site-packages/vocabsieve/local_dictionary.py", line 164, in dictimport
    self.importdict(d, lang, name)

    self.c.execute("""

The issue didn't occur earlier, and seems to have appeared only after i (unsuccesfully) tried to make a regex rule for dictionary lookups (that also failed to work, and bricked the regex functionality in its entirety), after which i was forced to reset my settings. Since then, importing sources of most (all?) sources seems to fail.
